VENTILATOR Filed June 5, 1941 zar/ msizkfmventor I I I Patented Feb. 2, 1943 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a ventilator and more particularly to such a device adapted to be installed upon a toilet of conventional design.

The principal object of the invention is the provision of means for elfecting the removal of undesirable odors from a toilet of the water closet type.

A still further object of the invention is the provision of means capable of attachment to a conventional water closet toilet bowl or seat for effecting the removal of undesirable odors therefrom.

The invention illustrated and describedherein, has been designed to eiTect the removal of objectionable odors from the area about a toilet bowl of the water closet type and comprises the positioning of an adapter member either upon the uppermost edge of the toilet bowl or beneath the toilet seat thereon. The said adapter adapted to communicate with a suitable suction blower for efiecting the removal of air from the toilet bowl area.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a top plan view of an adapter adapted to be positioned in under a toilet seat and adjacent the bowl.

Figure 2 is a top plan view of a suction blower arrangement and is illustrated in operative relationship to the device shown in Figure 1.

Figure 3 is a side elevation of the device shown in Figure 1.

In Figure l of the drawing the invention is illustrated and comprises a U-shaped" hollow member 24 provided on its innermost edge with a plurality of orifices 25. The member 24 is adapted to be positioned beneath a conventional toilet seat or clipped to the rim of a conventional toilet bowl. A partition 26 separates the member 24 into two separate and distinct air conducting channels 21 each of which is formed of flexible material and are adapted to establish communication with a suction blower I 6A such as illustrated in Figure 2 and hereinafter described.

By referring to Figure 3 of the drawing, a side elevation of the adapter member 24, will be seen which adequately illustrates the compact form of this device.

The suction blower 16A adapted to exhaust into a suitable air conduction duct or into a hollow partition as may be desired. In any case the resulting action is the removal of air and any objectionable odors that may be present from the area of the toilet bowl and the forcible direction of the same through the conduction duct l! or hollow partition as the case may be. The suction blower preferably employed, as illustrated in Figure 2, comprises a pair of centrifugal blowers IGA adapted to be revolved by means of an electric motor M positioned therebetween, which in turn is connected to a suitable source of electric current and controlled by means of a switch (not shown) so that the same may be operated at will. For example; a pressure operated switch attached to the toilet seat may be employed if desired..

It will thus be seen that the ventilator shown and described herein comprises means capable of effecting the removal of objectionable odors from the areas adjacent the toilet bowl and it will be obvious that the suction necessary to create the flow of air into the device may be located through a partition near the device or in any area, described, so long as suitable tubular connections are established. It will also be seen that the device is of simple formation and efficient in operation and entirely capable of performing its purpose due primarily to the dual application of the double air intake channels, tubular connections, and suction blower used. It will be seen that a device such as heretofore described, in order to be workable must provide an adequate and substantial flow of air therethrough, and the invention herein disclosed is believed to reside in the specific structure of the device making this possible.

What I claim is:

1. A ventilator ring adapted to be attached to a toilet and comprising a U-shaped hollow body member, a plurality of orifices formed in the said hollow body member about its innermost edge, a partition formed in the said hollow body member and a pair of flexible tubular members in communication with the said hollow body member, one positioned on either side of the said partition, and so arranged that air may be withdrawn therethrough.

2. In a device of the class described comprising a hollow body member of approximate U shape adapted to be positioned beneath a toilet seat, a partition formed in the said hollow body member at the base of the U shape, a plurality of openings formed in the said body member and communicating with the interior thereof together with a ai rof flexible tubular members communicating with the said hollow body member at points adjacent the base of the U shape thereof and on either side of the said partition, the said flexible tubular members adapted to communicate with a suction blower.
